Set prices for different paper sizes.
Save the price list.

Minimum Chargeable Amount
When a guest's print job costs less than the minimum chargeable amount for the transaction currency, the system automatically charges the minimum amount instead. Fees are calculated on the final charged amount (after the minimum is applied), not on the original job cost.
Example: A print job costs €0.40, but the guest is charged €1.00 (the EUR minimum). Stripe fees apply to the €1.00 charge.
